And the little one said, ROLL OVER

My roommate would snore very loudly every night, so I asked him if it was okay if I could yell at him to tell him to roll over.  Every night I did it, I asked him in the morning if it was okay, and he ALWAYS said yes.  After about six months, I woke him up to tell him to roll over, he chewed me out.  The next morning, he told me how I need to be more considerate of his sleep, and how I am being very rude for waking him up in the middle of the night.
